Carbon launches DB 4000 denture base resin for digital dentures
FDA-cleared material targets higher fracture toughness and print accuracy than the category leader
Carbon has launched DB 4000, a high-impact denture base resin engineered for dental labs producing 3D printed digital dentures on the company’s M-Series printers. The material is FDA-cleared and compliant with ISO 20795-1, the international standard for high-impact denture base resins.
Carbon named the resin for its work of fracture: 4,000 joules per square meter, tested at 37 degrees Celsius in water under modified ISO 20795-1 conditions. It is also a claimed 31% tougher than the published work-of-fracture results of the category leader for denture base resins.
Accuracy and workflow
Carbon reported that DB 4000 averaged 97% global accuracy within plus or minus 130 microns and 95% intaglio accuracy within plus or minus 100 microns in its internal validation testing.
The resin uses a single-cure, one-part workflow designed to fit into labs’ existing digital denture process without additional materials or processing steps. DB 4000 is built for Carbon’s Automatic Print Preparation software, part of the company’s AO Suite, and as of its 2026 launch is available exclusively on Carbon M-Series printers.
Availability and pricing
The resin ships in four gingiva shades — Light Pink, Original Pink, Dark Reddish Pink and Dark Meharry — intended to cover light, standard and deeply pigmented tissue tones. Carbon said DB 4000 carries a more competitive cost per part than leading alternatives, based on manufacturer suggested retail pricing, and that it is available now in the United States for dental labs validated on Carbon’s M-Series printers.
“DB 4000 is the product of an obsessive focus on the mechanics that actually determine whether or not a denture base holds up in the real world,” said Jason Rolland, Ph.D., Chief Technology Officer at Carbon. “We didn’t just want to make an incremental improvement over the category leader — we wanted the data to make the case on its own. That’s why the number is in the name.”
“DB 4000 is a clear example of how Carbon’s platform, hardware, software, and materials engineered together, let us bring dental labs a material with strong performance across the metrics that matter most, at a more competitive cost per part,” said Phil DeSimone, Co-Founder and Chief Executive Officer at Carbon.
“This launch reflects our continued investment in the digital denture market and our commitment to giving labs better tools, and better margins, to run their businesses.”
